摘要： An example system includes at least one acoustic sensor configured to generate at least one time-dependent acoustic data signal indicative of an acoustic signal generated by a thermal spray system performing a process associated with a plurality of process attributes. The example system includes a computing device including an acoustic data signal module and a control module. The acoustic data signal processing module may transform the at least one time-dependent acoustic data signal to a frequency-domain spectrum. The control module may determine a process attribute of the plurality of process attributes that deviates from a predetermined operating range by identifying at least one characteristic of the frequency-domain spectrum, selecting at least one component of the thermal spray system based on the process attribute, and controlling the thermal spray system to adjust the process attribute toward the predetermined operating range by sending a control signal to the at least one component.

摘要： There is disclosed a method of depositing, by a filament delivery device, a filament on a substrate defining a major surface to form an unsintered layer, the filament including a powder and a binder, the powder including a metal or alloy; removing substantially all of the binder; and sintering the unsintered layer to form an abradable layer for the substrate defining the major surface. There is also disclosed an additive manufacturing system comprising: a substrate defining a major surface; a filament delivery device; and a computing device configured to: control the filament delivery device to deposit a filament on the substrate, the filament including a powder and a binder, wherein the binder is configured to be substantially removed from the filament and the powder includes a metal or alloy configured to be sintered to form an abradable layer.

摘要： A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a sacrificial binder and a powder including a shape memory alloy (SMA). The method also may include removing substantially all the sacrificial binder from the fused filament fabricated component to leave an unsintered component; and sintering the unsintered component to join particles of the SMA and form an SMA component.
